The cross constrictor knot is similar to the double constrictor knot and has therefore similar characteristics. Any difference is because the two riding turns cross and therefore ride each other; this gives an additional jamming or locking effect.

The cross constrictor knot is also similar to the strangle knot and is therefore similar in characteristics to that one too. Any difference is because it has an additional riding turn that crosses the existing riding turn, and that the ends come out not from the side but from in between turns; this gives additional jamming or locking effect.

The cross constrictor knot is harder to tighten, harder to untie, more stable, builds more knot height than the double constrictor knot, more knot width than either constrictor knot or the strangle knot due to 3 turns rather than 2.

Variations involve starting with an underhand knot instead of an overhand knot, and passing the middle of one side over the other side rather than under. There are effectively only two variations starting with a simple knot (overhand or underhand); The difference is in the direction of the topmost riding turn:

The side leaving the simple knot on top is tucked under the other side : This variation is a strangle knot with an additional riding turn across its riding turn. The bottom riding turn in this variation runs in the grove of the simple knot, is therefore likely to have slightly lower profile, and has more friction surface.

The side leaving the simple knot on top has the other side tucked under itself : This variation is a constrictor knot with an additional riding turn across its riding turn. The bottom riding turn in this variation crosses the grove of the simple knot, is therefore likely to have slightly higher profile, and has more friction causing pressure on a smaller friction surface.
